3&period;Main Features1&rpar; Fast speed and high efficiencyWhen HF starts&comma;the molecules in the dielectric material will be polarized in very short time and heated&period;HF power only heat polar molecules&period;It will not heat dielectric material&period;HF heating is 3-5 times faster than hot steam&period;So it can save the power and improve the efficiency&period;

2&rpar; Uniform heatingHigh frequency heating is dielectric heating&period;It forms electric filed with positive and negative pole&period;HF power can penetrate material deeply&period;The waster or glue molecules in the material will get heated themselves by friction among molecules&period;In this way&comma;they get heated from the core material&comma;much more uniformly&period;

3&rpar; Good applicabilityHigh frequency heating can heat kinds of thickness material&comma;such as 2-3mm venner surface lamination&comma;1000mm thick engineered wood gluing&period;And different frquency can meet different material requirement&period;13&period;56MHZ is suitable for PVC heating and gluing 27&period;12MHZ is good for line production &period;4&rpar; Strong controllabilityHigh frequency heating is easy control and suitable for automatic production&period;Take HF edge gluer for example&comma;HF can equip well with hydraulic system&comma;electrical system can finish the whole process together&period;It can also well cooperate with last procedure&period;

1&rpar;&period;High strength steel structural oven body&period; This makes the whole machine stronger and more leak-proof of vacuum&period;2&rpar;&period;High frequency generator This is the core of this machine&comma; all procedures and main technology are inside&comma; Including PLC&comma;electric valve etc&period;&period;3&rpar;&period;Cooling tower This part is mainly used in hot weather&comma; the main usage is to cool the internal temperature&comma; guarantee the drying speed and quality&period; 4&rpar;&period;Timber cart We have both full-auto feeding mode and manual feeding model&comma; but the full-auto is only used on 8&sol;10&sol;12&sol;15cbm models&comma; because the smaller doesn't need this&comma; the loading quantity is enough to be push into the oven by workers&period;5&rpar;&period;Stainless condenser This parts are also to reduce the internal temperature when drying&comma; it will let the steam change into water droplet&comma; to guarantee the drying speed and quality&period;6&rpar;&period;Pressure system We have both hydraulic and pneumatic&comma; that means common oil pressure system and air pressure system&comma; they are to prevent the wood becoming bend and crack&period;7&rpar;&period;Perforated aluminum plate and wooden bar The perforated aluminum and corpper strips promote electronic cycle to improve the speed of heating&comma; and these two parts are to separate by wood bar to dissipating heat quickly&comma; guarantee the drying speed&period; 8&rpar;&period;Final moisture measurementThe moisture can be reduced from 60&percnt; to 8&percnt; even 6&percnt;&comma; only need to 3- 7 days each batch&period;

6&period;High-frequency heating and microwave heating are much different even if they can achieve wood drying inside and outside at the same time&period; 1&period;&rpar; Microwave heating uses electromagnetic wave&comma; but high frequency heating uses the electric field heating&period;2&period;&rpar; Microwave heating frequency is very high&comma; general in 900 MHz to 2400 MHz&comma; so its penetration rate is poorer&comma; the thickness of wood can not more than 40 mm&comma; otherwise the heat is uneven inside and outside&period; The frequency of HF generally in 6&period;78 ~ 13&comma;56 MHz&comma; for hundreds of mm thickness of the wood can achieve uniform heat internal and external&period;
